I'm kind of slammed, time wise at the moment but will see what I can do later.
Basically I figured most JW's might dare to look at old copies of their own magazine so all I did is do a Google search of "1914 generation" and clicked on "Images" and printed out the covers of old magazines that featured prophecies that time bore out as false when they failed. I circled the dates of the magazines to be sure they realized how old they were. I keep a similar packet near the front door for the rare occasion that a JW calls on us.
It seems to have an impact because how can they argue with their own literature?
The idea is to show them that generations of JW's have come and gone and what they think is new, was going on long before they came onto the scene
The last page of the "packet" was typed out and included the message that I showed in my original post.
